They all actually seem to be great comparisons. Kaepernick and Mariota both got the best elite speed and are best in a zone read offense. Griffin and Bridgewater are the best pocket passers. Manziel and Wilson both can scramble around to make plays and are best outside of the pocket due to their small height.

I wouldn't be sir prized if he passed McCoy on the depth chart. I think he might have a better arm and accurate arm then him from the highlights I thought. He also got some wheels too help us prepare for QB's as Wilson , RG3 and other runners etc.

I heard that Sylvester Stallone wrote The Expendables with The Alex in mind. He had to keep it realistic though and split The Alex's abilities into multiple characters. Stallone thought that critics would pan it for being too far-fetched if he just had one character effing everyone up.
